I am sleepy again

[darkfenriz]

as continuation of my previous post:sleepy man's question

my question is:
if problem with stability is coused by phase shitf in RF and we use some RC filters for freqeuncy compensation, which also adds phase shift- why not use something like 2nd or 3rd order Bessel LC filter within FBL??

looking forward to comments

You can have any order frequency compensation you want. Second order is not that uncommon. The problem is that to make it stable you need to do more complex calculations than for simple first order, or do a lot of fiddling to find an empirical solution.

but bessel filter gives maximum attenuation at minimum phase shift , am I right?
